Philco Radio Time, Bing Cosby and the Magnetic Tape

"In June 1947, before Ampex really got involved, I was invited to give another demonstration -- this time for Bing Crosby. He had been with NBC until 1944 [actually, until May of '46], doing the Kraft Music Hall live. He's a very casual person, and he resented the regimentation imposed by live broadcasts. Some weeks he wasn't in the mood and hated doing a broadcast. At other times he was ready to do two or three at a crack. He didn't like having to keep an eye on the clock and being directed to speed things up or draw them out. [...]

Bill Palmer and I had been using tape for soundtrack work (he already had a going business in the film industry before we joined forces), where magnetic recordings were far better in quality and more easily edited than the optical tracks that were standard for films at that time. We were introduced to Murdo McKenzie, the technical producer of the Crosby show, through our Hollywood contacts. And after our demonstration we were invited back to record the first show of the 1947-48 season. Crosby's people didn't say, 'You have the job.' They only wanted to see how tape would compete with the disc system they had been using."
